In order to study the effect of turbulence on submarine imaging system, an optical experiment system is built using pump and tank to make the turbulence area with controllable water flow velocity. The CCD is used to imaging the sinusoidal fringe and the image quality is analyzed. The imaging results with various water turbidity and flow velocity are obtained through the control of imaging experiment environment. The modulation transfer function (MTF) is extracted to analyze the results. Experimental results show that the particle scattering causes modulation contrast declines in the whole spatial frequency. The effect caused by turbulence scattering is more obvious on the high frequency. With the increase of inlet flow velocity and the attenuation coefficient, the MTF curves show quick downward trends. The image distortion and decline of resolution are caused by the particle and turbulence scattering in the turbulent environment.
